EEVblog 1557 - Micsig SigOFIT Optical Fibre Probe + GaN Experiment
Review of the new Micsig SigOFIT Optical Fibre oscilloscope probe, including a practical demonstation of the incredible CMRR range of opticallly isolated probing of a 300V GaN transistor driver circuit.
And a direct comparison with the HVP-70 high voltage differential probe to show you the incredible game changing difference an optical fibre probes makes.
